Offering discounts of up to 60% off standard rates, the hotel deals will be available in New York, Las Vegas, Los Angeles, Miami, Chicago, Boston and San Francisco to start.

Utilizing a similar concept to HotelTonight, Jetsetter Now offers deep discounts beginning at noon each day. A limited number of hotel rooms in each category are available, but booking, similar to Jetsetter’s “mystery” sales, is opaque, meaning that travelers will know if the hotel is “hip” or “contemporary” but not where exactly it is located or what its name is.

To participate, the hotels must already be Jetsetter-verified (meaning that an editor has personally visited and reviewed the property) and have a member review rating of 85% or above. If available, guests can book up to four nights through the app at a special rate.

Inventory will display as available or “sold out” as hotel rooms are booked. Like Travelocity’s lastminute.com, payment can be completed by scanning your credit card and the app is fully Passbook integrated.

Rob Deeming, Jetsetter.com general manager, spoke to us yesterday about the application, discussing how it is a logical extension of the brand, where travelers are excited to book verified and reviewed inventory at a reduced price, but are often frustrated that their counterparts offer only two to four-star “mystery” hotels.

He doesn’t worry that the mysterious nature of hotels booked will bother travelers, as he says many are already flocking to the site’s existing mystery flash sales. The opaque nature of the booking process encourages luxury hoteliers to share their unused inventory with Jetsetter, he explains, because they are often reluctant to showcase a discounted rate for fear that travelers will grow accustomed to waiting until the last minute to book.

In our trial case, we “booked” into the Surrey, an upscale uptown hotel that can charge upwards of $1,000 for a one-night stay. Through Jetsetter Now, the price was just $290 per night.

We also loved the scan and go credit card feature, which made booking simple while on the go.

What do you think? Will this new development spur you to book a last minute escape? The application is free in the app store for iPhone and iPod touch.
